Book excerpt: This book examines Russian influence operations globally, in Europe, and in Russia’s neighboring countries, and provides a comprehensive overview of the latest technologies and forms of strategic communication employed in hybrid warfare. Given the growing importance of comprehensive information warfare as a new and rapidly advancing type of international conflict in which knowledge is a primary target, the book examines Russia’s role in Global Knowledge Warfare. The content is divided into three parts, the first of which addresses conceptual issues such as the logic of information warfare, the role of synthetic media, and Russia’s foreign policy concepts, including the impact of the COVID-19 pandemic on influence operations. The second part analyzes technological, legal and strategic challenges in modern hybrid warfare, while the third focuses on textual, cultural and historical patterns in information warfare, also from various regional (e.g. the Western Balkans, Romania, Ukraine, and the Baltic) perspectives. The book is primarily intended for scholars in the fields of international relations, security and the military sciences who are interested in Russian foreign policy and influence operations, but also their impact on the global security environment.
